As the branching fingers of Sydney Harbor come into view at the end of a trans-Pacific flight, yachts dot the dark waters below and then sails of the Opera House glisten, announcing your arrival in one of the world's most glamorous cities. In cosmopolitan Sydney, Melbourne, and the Sunshine State of Queensland natural beauty and urbane sophistication come together in different proportions and in different ways, but they come together just the same. Australia luxury homes reflect this blend of nature and man-made splendor, from elegant contemporary showcases in the city to waterfront retreats overlooking the Great Barrier Reef.
